It is recommended to use EnvironmentObject in SwiftUI to pass data or state that should be accessible to many views in the hierarchy, without needing to explicitly pass them through each level.

It should be used when:

  • There is a global state, such as user settings, app theme, or authentication data.
  • Many child views need to automatically update when the data changes.

Example:

class UserSettings: ObservableObject {
    @Published var username: String = ""
}

// In the root view
@StateObject var settings = UserSettings()

// Passing in the hierarchy
ContentView()
    .environmentObject(settings)

// In the child view
@EnvironmentObject var settings: UserSettings
